The log collection operation of management equipment to managed devices comprises the steps:
Step 1, attendant specifies the managed devices of required collection by network management software operation interface and daily record starts, end time information, and submits this request to the network management software.
Step 2, the collection demand that the network management software provides according to operating personnel, by management information bank (ManagementInformation Base, referred to as the MIB) information of agreement, the following field (SNMP OID) to managed devices carries out SNMPSET operation one by one:
A, use by the network management software be managed devices distribute unique identification, preferably, can arrange the character string (separating with " _ ") that G.M.T. (Greenwich Mean Time, referred to as GMT) the millisecond number that issues acquisition operations instruction time point combines is the unique identification of this operational order.
B, collection daily record time started (such as, representing with YYYYMMDDHH form).
C, collection daily record end time (such as, representing with YYYYMMDDHH form).
File transfer protocol (FTP) (File Transfer Protocol, referred to as the FTP) address of service that D, the network management software provide.
The FTP serve port that E, the network management software provide.
The FTP service-user name that F, the network management software provide.

Step 5, managed devices, according to acquisition operations instruction, gathers satisfactory daily record from business journal file, is formed and reports journal file, and by this compressing file, the such as file of boil down to .zip form.The filename of the file of this .zip form can be the unique identification of operational order.
Step 6, the file of .zip form is uploaded to the network management software by FTP by managed devices.
Step 7, managed devices reports SNMP TRAP to the network management software, wherein, can comprise following information:
The unique identification of A, this acquisition operations instruction.
B, files passe result, such as, character string " 0 " represents to be uploaded successfully, and other character string is error description.
C, this file are uploaded to the path (such as, serving root relative to FTP) of FTP service.
Step 8, the network management software receives and resolves SNMP TRAP, such as:
A, files passe result are " 0 ": initiatively push collection successful information to operating personnel, alert downloads the journal file uploaded.
B, files passe result are not " 0 ": initiatively push collection failure information to operating personnel, reporting errors information.
Step 9, if (such as, in 30 minutes) do not receive corresponding TRAP(according to the unique identification of acquisition operations instruction as comparison condition in the given time), then initiatively push collection failure information to operating personnel, report acquisition operations time-out information.
Visible, by the above embodiment of the present invention or preferred embodiment, provide a kind of implementation of a kind of asynchronous communication based on snmp protocol, namely, by the connected applications by SNMP SET/GET and SNMP TRAP, the snmp protocol solved in correlation technique does not provide asynchronous communication mechanism to meet the problem of the demand of complicated business, thus provides the Business Processing mechanism of asynchronous communication based on existing snmp protocol.
